DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which are shown, by way of illustration, specific embodiments in which the disclosed subject matter can be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the disclosed subject matter.

According to various example embodiments of the disclosed subject matter as described herein, there is disclosed, illustrated, and claimed a trash receptacle for separating liquids and solids. The example embodiments disclosed herein provide an apparatus, system, and method implemented as a trash receptacle for separating liquids and solids, which can be used in a variety of applications. The trash receptacle for separating liquids and solids of various example embodiments can be a two-piece recycling separation system designed with two orifices, which can be mounted on top of a trash container or other trash or garbage container. A trash orifice of the trash receptacle provides a pass through chute straight into the trash container. A liquid orifice of the trash receptacle provides a catch area for liquid waste. When liquid is poured in the liquid orifice, the liquid is funneled down a drain and stored in a reservoir tank for future disposal. Once the reservoir tank is full, the tank can be removed and the waste liquid can easily be discarded or recycled by removing a screw cap and pouring the liquid content into a sink/drain or proper recycling container. The solid trash placed in the trash orifice passes directly through the lid and reservoir tank of the trash receptacle. The solid trash is directed dry into the trash container. Once the trash container is full, an individual can lift off the lid and reservoir tank of the trash receptacle and remove the solid trash from the trash container.

In an example embodiment, the two-piece system comprises a fitted plastic lid unit 5.5″×20.25″×11.5″ (H×W×D) and a plastic reservoir tank 4.5″×20″×11.25″ (H×W×D). The lid unit is made with a 7.25″×8″ pass through chute for solid trash and a round 7″ sink area with a catch drain for waste liquids. The lid unit is designed to be mounted on top of the reservoir tank when the trash receptacle is assembled. When the lid unit is mounted on top of the reservoir tank, the drain tube of the lid unit depresses the top of a plastic spring loaded check valve. When the trash receptacle is assembled, liquid poured in the sink area of the lid unit flows freely into the reservoir tank. Once the reservoir tank is full, the lid unit can be removed, thereby causing the check valve to close and providing a liquid tight reservoir tank. The reservoir tank is then ready to be transported and content disposed of using a proper recycling method. The assembled trash receptacle can be mounted on an opening of any 23-gallon rectangular trash container. The disclosed embodiments can be universal, fitting many different configurations and shapes of trash containers with slight variations of measurements.

Referring now to FIGS. 1 through 9 , example embodiments of the trash receptacle 100 for separating liquids and solids are illustrated. FIG. 1 illustrates a blown-up version of an example embodiment interacting with a trash container 200. Referring now to FIG. 1 , the trash receptacle 100 includes a lid unit 110 and a reservoir tank 120. The lid unit 110 includes a sink area 112 for receiving waste liquids and a chute area 114 for receiving waste solids. The sink area 112 and the chute area 114 can be fabricated as a single integrated component. The sink area 112 includes a stainless-steel grate 116 to strain off any large items that may be placed in the sink area 112. Stainless steel screws 118 can be used to hold the stainless-steel grate 116 in place in the sink area 112. The lid unit 110 includes the sink area 112 for receiving liquids and the chute area 114 for receiving solids, which pass through a corresponding chute 124 of the reservoir tank 120 and straight into the trash container 200. The stainless steel screws 118 can be configured so that the stainless-steel grate 116 can be attached in place in the sink area 112 and detached for cleaning purposes.

In the example embodiment shown in FIG. 1 , the sink area 112 also includes a drain with a connecting tube 119 at the base of the sink area 112.

FIG. 19 illustrates a rear view of an alternative example embodiment of the self-contained and portable/mobile waste liquid collection and storage unit. FIG. 20 illustrates a cutaway view of an alternative example embodiment of the self-contained and portable/mobile waste liquid collection and storage unit showing the sink, drain, and P-trap. FIG. 21 illustrates a top view of an alternative example embodiment of the self-contained and portable/mobile waste liquid collection and storage unit. FIG. 22 illustrates a bottom view of an alternative example embodiment of the self-contained and portable/mobile waste liquid collection and storage unit. Details of the illustrated alternative embodiment are provided below.

One purpose of the alternative example embodiment of the self-contained and portable/mobile waste liquid collection and storage unit with an integrated sink is to allow individuals from children to adults a place to pour unused liquid. The alternative example embodiment collects the unwanted liquid and stores the unwanted liquid in a liquid holding reservoir until the reservoir is full, allowing a person to wheel the portable/mobile trash receptacle to the appropriate recycling system for disposal.

In example embodiments, the alternative example embodiment of a self-contained and portable/mobile waste liquid collection and storage unit with an integrated sink is denoted herein as the PourAway™ Cadet™ (Cadet) or the unit. In the alternative example embodiment, the Cadet is a self-contained portable/mobile liquid recycling and storage receptacle. The Cadet is made by a rotational molding method using High-Density Polyethylene Plastic (HDPE). The design of the Cadet is unique and contains features specific to collection, storage, transport, and disposal of unwanted or waste liquids.

In example embodiments and with reference to FIGS. 16 through 22 , the Cadet's collection method starts with a molded-in 10″×9″×7″ deep sink 1110. The sink is connected to an internal P-Trap 1129. Having a P-Trap provides an airtight seal, which prevents smells and vapors from leaving the unit. On the side of the unit is a 4-inch watertight cap 1111 to allow servicing and cleaning of the inside of the tank and P-Trap. The void inside of the unit 1101 can serve as a waste liquid reservoir or holding tank.

In an example embodiment, the Cadet can store up to 15 gallons (weight equivalent of 125.5 lbs.). The unit is stable and sturdy and is designed to hold liquid and readily move large amounts of liquid, which can produce excessive weight. The Cadets HDPE wall thickness is ¼ inch. Mobility is provided using 8-inch steel hub rubber wheels 1114. The wheels are mounted on a ½ inch steel axle 1112 and held in place by stainless-steel axle end caps 1113. The bottom front of the Cadet is designed with two small feet or protrusions 1115 at the base and in front. These feet are specifically designed to hook on to the wall of a custodial drain and will allow the Cadet to be tilted forward for unmanned drainage. The unit is very ergonomic even when full. A foot peddle 1123 has been designed into the bottom of the unit for leverage to stabilize the unit prior to movement. The Cadet can easily be tilted back and maneuvered like roller luggage.

The clear volume level tube 1122 embedded just above the foot peddle in the back of the tank provides easy viewing of internal liquid levels and identifies when the tank is full.

The bottom/base of the Cadet is tapered to its lowest level for drainage collection. A ¾ inch fitting 1131 is spin welded into the area and a ¾ inch fitting 1131 is threaded in. The fitting 1131 connects to a ¾ flex drain hose 1133, which is held in the close upright position by (2) two stainless steel hose clamps 1117. Once the hose is removed from the side of the Cadet and laid to a drain, the ball valve 1116 at the top of the hose can be opened for flow to escape the storage area. Thus, an alternative example embodiment of a self-contained and portable/mobile waste liquid collection and storage unit with an integrated sink is shown and described.

The various example embodiments disclosed herein solve the problem of liquids contaminating solids and recyclables in trash and thereby improve the related technology. The various example embodiments disclosed herein reduce costs for hauling unnecessary liquid weight, reduce CO2 gas production from landfills, and reduce the number one cause of workers compensation claims in the U.S., which is back injuries. The disclosed example embodiments offer a user the ability to separate his or her liquids from solids when discarding waste by offering a sink area in the trash receptacle, which is used to catch liquid, direct it to a liquid tight reservoir tank, and retain the liquid to be discarded at a future time.

By reducing liquids in trash, the energy used to haul the trash is reduced. Liquid has a weight of 8.3 lbs. per gallon. Thus, reducing weight of the trash reduce the energy and costs related to hauling the trash. Additionally, the disclosed example embodiments reduce the volume of liquid in landfills. Both of these benefits produced by the disclosed example embodiments help to reduce CO2 emissions and greenhouse gases. The disclosed example embodiments offer a way separate the weight of heaver liquids allowing the user the ability to pour liquids down the drain thereby providing organic liquid a free ride to the treatment plant rather than incurring the costly expense of transporting the liquid waste by truck to a landfill. Reducing weight and liquid from trash prevents the primary cause of worker's compensation and general liability claims in the U.S., which is back injuries and slip and fall incidents. No other mechanism offers a system by which a user can separate liquid from trash and store the liquid for later discard.
